General questions relating to Joomla! 2.5. Note: All 1.6 and 1.7 releases have reached end of life and should be updated to 2.5. There are other boards for more specific help on Joomla! features and extensions.
In my opinion I prefer Woocommerce. I found Virtuemart to be quite buggy and to have a ton of old code and just in general weird ways of doing things. That said, I havn't used Virtuemart in about a year, and it seems it's undergone a major upgrade.
Overall I'd say it's worth taking the time to set up a basic store with both systems and try them out for yourself. An e-commerce store can get complicated quickly and you want to be sure you chose the right platform for your needs.
